Question

The perimeter of a rectangular cuboid is 72cm. The height of the cuboid is 4cm. The length of the cuboid is 1 and a 1/2 times the breath. Calculate the length and breath of the cuboid.

Answer 1

length=$1\frac{1}{2}$breadth

Step-by-step explanation:

• length=$1\frac{1}{2} =\frac{3}{2}$breadth
• l=$\frac{3}{2}$b
• perimeter of rectangular =72
• 2*(l+b)=72
• l+b=36
• $\frac{3}{2}$b+b=36
• $\frac{3b+2b}{2}$=36
• 5b=72
• b=72/5
• l=108/5 are the breadth and length of cuboid.
